Question

我正在尝试解决这个SQL查询（用法语）

我有4个不同的表：CLIENT，COMMANDE（订单），DETAIL（订单）和PRODUIT（产品）

我必须在查询中提供尚未发出任何订单（COMMANDE）的'Namur'（即LOCALITE）客户的号码（NCLI）和名称（NOM）

我尝试了不同的东西，我在SQL快递中的最后一个代码是这个（当然不起作用。

 select NCLI, NOM
 from   CLIENT
 where  LOCALITE = 'Namur' and (NCLI in (select NCLI             
                                   from COMMANDE
                                   where NCOM in (select NCOM
                                                  from DETAIL
                                                  where QCOM not in DETAIL)))

有人可以帮我解决这个问题吗？

如果需要，这是我现有表格和插入内容的代码：

create table CLIENT
(NCLI char(4) not null,
 NOM  varchar(12) not null,
 ADRESSE varchar(20) not null,
 LOCALITE varchar(12) not null,
 CAT char(2),
 COMPTE decimal(9,2) not null,
 primary key (NCLI));

create table PRODUIT
(NPRO char(5) not null,
LIBELLE varchar(20) not null,
PRIX decimal(5,0) not null,
QSTOCK decimal(6,0) not null,
primary key (NPRO));

  create table COMMANDE
 (NCOM char(5) not null,
 NCLI char(4) not null,
 DATECOM datetime not null,
 primary key (NCOM),
 foreign key (NCLI) references CLIENT);

 create table DETAIL
 (NCOM char(5) not null,
 NPRO char(5) not null,
 QCOM decimal(4,0) not null,
 primary key (NCOM,NPRO),
 foreign key (NCOM) references COMMANDE,
 foreign key (NPRO) references PRODUIT);

Answer 1

为什么不试试这个：

select NCLI,NOM
      from CLIENT
      WHERE LOCALITE = 'NAMUR' AND NOT EXISTS(
                                            SELECT *
                                            FROM COMMANDE 
                                            WHERE CLIENT.NCLI = COMMANDE .NCLI)

Answer 2

这有用吗？

select c.NCLI, c.NOM
 from   CLIENT c
 where  c.LOCALITE = 'Namur' and c.NCLI NOT IN  (select NCLI             
                                   from COMMANDE)
